Though Adrian is skeptical of his new therapist at first, Dr. Bell was able to win his confidence though several small gestures (such as having Adrian's favorite bottled water available, a supply of wipes handy during their introductory handshake, and Dr. Bell's office containing a painting which previously belonged to the late Dr. Kroger).
Additionally, as a comfort to Adrian, Natalie pointed out that Dr. Bell's first name, Neven, is a palindrome. Adrian, however, points out that it isn't a "perfect" palindrome, because of the first "N" being capitalized. However, Monk eventually decides that Neven is a palindrome.
Neven is much more tolerant of Monk than Dr. Kroger.
He may have been named after Dr. Joseph Bell, the real life doctor who is the basis for Sherlock Holmes.
